Ergonomic backpacks for children and adults

描述（由申请人提供）：尽管现代便利，人类无论走到哪里都要运送相当大的重量。虽然在光滑平坦的地面上，小轮子的行李是有效的，但在这些限制区域之外，它们是无效的，而且增加了重量。因此，背包仍然是我们移动负载的首选解决方案。它们无处不在，由儿童和成人携带，代表着一个每年2.95亿美元的产业。儿童背的书包重量过大是一个重大的国际公共卫生问题（书包综合症）。但是用背包背东西对成年人来说也是一个潜在的问题，尤其是中老年人。我们现在携带了更多的技术（例如，笔记本电脑），增加的力量可能导致背部，颈部，肩部和膝盖疼痛和受伤，这可能会使人们不愿走路或阻止他们参加娱乐活动（如徒步旅行）。因此，背背包造成的伤害会导致第二个问题，即干扰维持心血管健康、减缓关节退化和肌肉萎缩的活动。基于我们的生物力学分析，我们在背包设计中提出了一个新的概念，“悬载”。在最近发表在《自然》杂志上的一篇论文中，我们表明，走路时的峰值动态力可能是静态力的两倍，跑步时的峰值动态力可能是静态力的三倍。我们的原型大容量人体工程学背包可以减少82%的行走加速度，从而降低代谢率。我们的背包在跑步过程中进一步减少了86%的加速度，使负重跑步更加舒适。为了将我们的创新带给最受影响的群体，儿童和老人，我们必须将技术小型化，以适应更小的包装（一个日包）。此外，由于重量和便携性是问题，从我们大容量成人背包的“外框”设计转变为轻重量的“内框”设计也很重要，例如，可以放入学校的储物柜。要实现这一目标，必须实现以下目标。目标# 1。优化符合人体工程学的悬挂机制，为成人背包的目标#2。内框“人体工程学背包”佩戴者界面的设计与实现测试——比较人体工程学背包与普通背包。评估人体工程学背包的替代悬挂系统。开发背包和步行人的预测模型，以帮助优化设计。在第一阶段结束时，我们将使成人背包商业化。基于第一阶段开发的生物力学和制造见解，在第二阶段，我们将为中学生开发符合人体工程学的日包，我们将承受更大的重量，易于操作和成本限制。第二阶段：中学生内框人体工学日包的开发。在开发出成人人体工程学背包后，我们将再次创新，为中学生打造更小、更轻、更便宜的人体工程学背包。公共卫生相关性：在整个西方世界，人们一致认为学生上学时背的书包太重，导致背部和关节疼痛和受伤。虽然负重的一些力来自于它的重量，但当我们走路或跑步时，这些力会增加三倍，大大增加疼痛和受伤的可能性。闪电背包公司发明了一种全新的背包，悬挂式背包，它消除了与运动相关的高强度。成人和中学的日包版本将在这里开发，允许更健康的负载运输。

DESCRIPTION (provided by applicant): Despite modern conveniences, humans continue to transport considerable weight wherever they go. Although on smooth even surfaces, luggage with small wheels is effective, outside of these restricted arenas they are ineffective and add to the weight. Hence backpacks remain the preferred solution to move loads around with us. They are ubiquitous, carried by children and adults, and represent a $295 million dollar/year industry. The large weight of backpacks carried by children is a significant international public health problem (bookbag syndrome). But carrying loads in backpacks also represents a potential problem with adults, particularly the middle-aged and elderly. We now carry more technology (e.g., laptops) and the increased forces can lead to back, neck, shoulder and knee pain & injury which may discourage or prevent people from walking or prevent them from participating in recreational activities (such as hiking). So injury from carrying backpacks can lead to the secondary problem of interfering with activities which maintain cardiovascular health and slow the joint degeneration and muscle atrophy which comes with age. Based on our biomechanical analysis, we have developed a new concept in backpack design, "suspending-the-load". In a recent paper in Nature we have shown that peak dynamic forces can be twice as high as the static force during walking and 3-fold higher during running. Our prototype large volume ergonomic backpack reduces accelerative force by 82% during walking, leading to reduction of the metabolic rate. Our pack further reduces accelerative forces by 86% during running, making it comfortable to run with a load. To bring our innovation to the most affected groups, children and the elderly, we must miniaturize the technology to fit into a much smaller package (a daypack), Further, because weight and portability are issues, it is also important to migrate from an "external-frame" design in our large volume adult backpacks to a light- weight "internal-frame" design which can, for example, fit into school lockers. To achieve this, the following aims must be accomplished. Aim #1. Optimize Ergonomic Suspension mechanism for Adult daypack Aim #2. Design and implementation of wearer interface for internal-frame" ergonomic backpack Aim #3 Testing-Compare ergonomic daypack to normal daypack Aim #4. Evaluate alternative suspension systems for ergonomic backpack Aim #5. Develop a predictive model of the backpack and walking human to help optimize the design By the end Phase I we will have commercialized the adult daypack. Based on the biomechanical and manufacturing insights developed in Phase I, in Phase II we will develop an ergonomic daypack for middle- school students where we will be under greater weight, ease of operation and cost constraints. Phase II: Development of Internal frame ergonomic day pack for middle school students. After developing an Adult Ergonomic Daypack, we will innovate again to build a smaller, lighter and less expensive Ergonomic Daypack for middle school students. PUBLIC HEALTH RELEVANCE: Throughout the western world, it is agreed that the backpacks students carry to school are too heavy, resulting in back and joint pain and injury. Although some of the forces from a load comes from its weight, when we walk or run, these forces can triple, greatly increasing pain and the possibility of injury. Lightning Packs has invented a fundamentally new type of backpack, the suspended-load backpack, which removes the high forces associated with movement. Adult and middle-school daypack versions will be developed here permitting more healthful carriage of loads.
